HOLDER FOR STICK MATERIAL.

Specification of Letters Patent.

Patented June M), 1919.

Application filed November 9, 1918. Serial N 0. 261,839.

To all whom it may concern:

Be it known that I, F RANK GRANT, a citizen of the United States of America, residing at Westfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Holders for Stick Material, of which the following is a specification.

This invention relates to improvements in holders for stick material and more particularly to improved containers for material, such as shaving soap and the like, which containers are provided with feeding or dispensing means such that the stick may be conveniently, yet positively, extruded from or retracted into the container.

One object of this invention is to provide an improved holder, involving relatively rotatable members, one of Which constitutes a container for the stick of material, and a carrier movable axially within the container upon relative rotation of said members and provided with meansto positively and firmly grip the stick, characterized in that the stick gripping means are releasable when the carrier has been moved to its innermost position to permit extraction of the old and insertion of a new stick into the holder.

Another object of the invention is to provide a holder for stick material, such as shaving soap and the like, which holder is provided with relatively rotatable parts cooperating with an interengaged stick carrier, having means to positively grip and firmly hold a stick of the character mentioned, so that the stick may be positively pro ected or retracted from or into the holderand so that the stick remains in any position of projection or retraction to which it may be used in the ordinary manner without being itself manually held.

Another object of the invention is to provide in a holder of the general type described, a stick clutching means involving two separable jaws between which the stick .may be inserted and which may subsequently be moved toward one another at right angles to the sticks axis to grip the latter, said jaws being automatically held in stick gripping-position by the Walls of the container-within which it is adapted to be drawn.

Another object of the invention is to provide a holder made up of two relatively rotatable sleeves and a carrier movable within one of said sleeves and arranged to grip the stick of material, one of said sleeves having oppositely disposed cam grooves and the other having oppositely disposed guide slots,

the carrier having projections each designed vide a generally improved holder for material of the character mentioned.

Other features of the invention will appear in the following description and in the illustrative embodiment of the invention in the accompanying drawings, in which:

Figure 1 is an elevational view, with parts broken away, of a holder embodying the 1nvention;

Fig. 2 is a sectional elevation taken at right angles to Fig. 1 and showing the stick carrier in a different position:

Fig. 8 is a fragmentary sectional eleva tional view taken on the line 8 8 of 1g. 7.

Referring to these drawings 1n detall; the holder involves two relatively rotatable casings l0 and 11 which are disposed in closely fitting concentrical relation. One of these casings, as the inner casing 11, is provided with a flanged base piece12 the periphery of which is preferably knurled to permit the member 12, and thus casing 11, to be turned with one hand while the other casing 10 is held stationary with the other hand. The member 12 is suitably fixed to the lower end of the innercasing 11 and is preferably Each of the sections of a diameter at least equal to the outside diameter of the outer casing 10, whereby a shoulder or seat is formed for the lower end of casing 10.

The inner casing 11 is adapted to contain the stick material, such as shaving soap or the like for example. The stick, as s, is proje'ctable from or retractable into casing 11 when the casings 10 and 11 are relatively rotated. ,Thus, the stick 3 is held in a carrier 13 and at opposite points on the periphery of the latter are two projecting pins 14 each of which passes through a slot 15 in the inner casing 11 and into a cam groove, such as the screw thread 16 formed on the interior of the outer casing 10. The two slots 15, as indicated in Fig. 2, are oppositely disposed and extend axially of the casing 11 from points closely adjacent the opposite end of the casing. The grooves 16 consist preferably of helices of relatively small pitch. For example, the two grooves 16 shown are merely a double screw thread, as will be observed from Fig. 3, wherein opposite portions of successive convolutions lie at equal axial distances from the end of the casing. It will be readily understood that when one casing is turned relatively to the other the ins 14 will be moved along the screw threads 16 to move the carrier 13 axially of its casing 11.

replacement of the stick when desired. To

this end the carrier is made up of two semicylindrical sections 17 and 18 which, as indicated in Fig. 4, normally are held in substantially abutting relation by the cylindrical wall of casing 11. A hollow tubular member 19 passes diametrically through the mating sections 17 and 18 and is preferably suitably held, as by friction, to one section, as 17, the other section, as 18, being readily movable on the member to permit separation of the sections. The member 19, as best shown in Fig. 8, supports the described pins 14, by means of which the carrier 13- is moved within itscasing 10. Such pins 14 are mounted to yield axially and to this end a s ring 20 is provided within member 19 which tends to force both pins 14 axially outwardly to the extent permitted by the abutment of the flanged heads of the pins with the crimped in portions of member 19. One of the sections, as 18 is provided with a shouldered down portion 21 (Fig- 2) which, when the carrier 13 is moved outwardly from casing 11 to the limit (as defined by the abutment of pins 14 with the upper ends of slots 15), permitsthe section 18 to be moved radially away from the section 17 without in any way necessitating removal of the carrier 13 from the casing 11. 17 and 18 are provided two grooves 25 and 25 thin semi-circular upstanding wall 22 to encompass the stick 8, the base of which is of course supported on the upper faces of the sections 17 and 18. At intervals around the perlphery of the walls 22 projections 23 are provided, as shown in Figs. 7 and 8,

which projections will dig into and firmly grip the stick 8, when the two sections 17 and 18 are pushed together. The upper edge of each Wall 22 may be slightly turned over, as shown in Figs. 7 and 8, to produce very small flanges 23 which aid in gripping the stick 8. j

In order to permit the described elements to be conveniently assembled or taken apart, when desired, there are provided certain other desirable constructional features, as will now be described. The outer casing 10 is, as shown in Fig. 3, provided with a vertical groove 25 which extends from the lower terminus of .one helical groove 16 to. the lower end face of casing 10. As indicated in Fig. 6, there is a second similar groove 25 for the other helical groove 16 and the are arranged in diametrically opposite relation. Thus, when the carrier 13 has been moved inwardly as far as possible, both pins 14 will be alined with their respective slots 25 and 25' so that the outer and inner casings 10 and 11 respectively may be separated by moving one relatively to the other in an axial direction.

Any suitable means may be provided to restrain the casings 10 and 11 from relative movement in an axial direction. One simple and advantageous means, at present preferred, involves the provision of at least one projection 27 (Figs. 1 and 4) which is arran ed to ride in a circumferential groove 28 Figs. 2 and 3) to prevent separation of the casings. Preferably, although not necessarily, the projection 27 is arranged vertically in line with dicated in Fig. 1. By this arrangement, one of the described slots, as 25', may be utilized to receive the projection 27 and permit its passageto the groove 28. The other slot 25 is preferabl' made slightly smaller than projection 27 the arrangement being such that each of the slots 25 and 25 is capable of receiving the pins 14, but only one, as 25', is capable of receiving projection 7 The arrangement just described permits the axial separation of the casings 10 and 11 whenever the carrier 13 has been moved to its innermost position for then both pins 14 must necessarily alineewith their respective slots 25 and 25 and so also the projection 27, which is located in line with one slot 15; and thus with one pin 14, must aline with its groove 25. At all other positions of the carrier complete separation of the casings is not permitted, for although projection 27 each section is provided withv a relaone of the slots 15, asinmay periodically aline (once each revolugroove 25', the pins 14 obvlousl prevent removal of the outer casing 10. This arrangement, for retaining the casings 10 and 11 in assembled relation, is .considered an important and advantageous feature of the invention.

Another most important feature of the invention consists of the yieldable carnfollowers or pins 14. A single rigid pin of exactly the right length could of course be used, but, should the grooves 16 become the least bit gummed up or should the pin project slightly farther from one than from the other side of the carrier 13, a binding action would result. The described mounted pins 14 avoids this difliculty and yet insure a certain engagement with the necessarily shallow cam grooves 16 at all times. The pins 14, also permit the carrier 13 to be readily inserted into or withdrawn from casing 11, when desired. After the removal'of casing 10, as already described, the pins 14 are accessible as shown in Fig. 4 and if the carrier is moved'to its outermost position and both pins 14 pressed inwardly to clear the inner wall of casing 11, the carrier 13 may then be readily withdrawn. The assemblyofthe carrier 13 in casing 11 involves merely a reversal of the described operations. A most essential feature of the present int1 on) with its Y vention consists of the arrangement whereby the stick can be removed from or replaced in the holder without taking the holder apart. This result is important in a holder of the present character wherein means are provided to positively clutch the stick so that it can be moved positively in either direction. As distingulshed from mere adhesion or frictional engagement, the described arrangement provides positive means to clutch,

- grip and dig into the sides of the stick so that it is firmly held to the carrier without leaving space sufficient for stick 8 to wabble. The projections 23 act as jaws and dig into the stick from-opposite sides and at right angles to its axis.

In use, the casing 10 may be held stationary while the member 12 is turned until the carrier 13 has been moved into-the position shown in Fig. 2. The two parts of the carrier 17, and 18, may then be spread apart to receive the stick 8 and thereafter closed together to grip the stick without serious abrasion. The member 12 is then turned in an opposite direction until the stick 8 has been wholly drawn into its container 11. Thereafter, the user merely turns the member 12 to project stick 8 sufficiently for use and after use retracts the stick within the casing. The pitch of grooves 16 is purposely made such that the stick is retractable only by turning the casings 10 and 11, the one relatively to the other. That 1s a push on the yieldingly said member,

ping position sticks, as when it is pressed against theface 111 normal use, willnot retract the stick.

It is also to be noted that the stick 8 has 1 15. Such shaving action soon results in gulnming up the interior of the casing and produces undesirable unsanitary conditions. The arrangement of the vertical guide slots in the inner casing, rather than providing the cam slots 16 of many convolutions therein, is also important for similar reasons.

The invention ha been disclosed herein for illustrative purposes, but the scope of the invention is defined by the appended claims rather than by the foregoing description.

What I claim is- 1. In a holder for stick material, a casing to contain the stick, a carrier movable axially in said casing, a member rotatable relatively to said casing, cooperating and interengaging means provided on the carrier, casing and member to move the carrier when the casing and member .are relatively rotated, and clutching means on said carrier to positively grip the stick, said means being separable when the carrier is moved to its outer position in said casing to permit extraction or insertion of a stick.
